a rectangular wall with a length of 10x and width of 20 x has a rectangular doorway with a length of 5x and a width of 2x. What

Shtirlitz [24]

Answer:

∴ The the surface area of the wall is $190x^{2} \ square\ unit$ .

Step-by-step explanation:

Given that,

The length of rectangular wall is $10x$ .

The width of rectangular wall is $20x.$

The length of doorway is $5x.$

The width of doorway is $2x.$

and, we have to find the surface area of rectangular wall.

Now,

The length of rectangular wall is $10x$ .

The width of rectangular wall is $20x.$

∴ Total surface area of a rectangular wall $= Length\ of\ wall\times Width\ of\ wall$

$= 10x\times 20x$

$=$ $200x^{2} \ square\ unit$

Total surface area of a rectangular wall is $200x^{2} \ square\ unit$ .

Again, The length of doorway is $5x.$

The width of doorway is $2x.$

∴Total surface area of doorway $=Lenght\ of\ doorway\times Width\ of\ doorway$

$=5x\times 2x$

$=10x^{2} \ square\ unit$

Total surface area of doorway is $10x^{2} \ square\ unit$ .

∴The remaining surface area of a rectangular wall is $=$ $200x^{2} -10x^{2}$

$=190x^{2} \ square\ unit$

∴ The the surface area of the wall is $190x^{2} \ square\ unit$ .

When you have two side lengths of 2in and 4.5in What is the other side length?

nika2105 [10]

Answer:

The solution for the other side length is the interval

(2.5,6.5)

Step-by-step explanation:

I will assume that is a triangle

we know that

The <u><em>Triangle Inequality Theorem</em></u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

Let

x ---> the measure of the third side

Applying the Triangle Inequality Theorem

1) $2+4.5 > x$

$6.5 > x$

Rewrite

$x < 6.5\ in$

2) $2+x> 4.5$

$x> 2.5\ in$

therefore

The solution for the other side length is the interval

(2.5,6.5)

Which is a true statement about an exterior angle of a triangle

Harlamova29_29 [7]

Answer:

Step-by-step explanation:

The exterior angles are out of the triangle at all times and it adds up to make 180 with anyone of the inside angle of the triangle.

The pair also rests on the same flat/straight line and that makes a pair.

Therefore we can say that it is formed by a linear pair/group with one of the interior/inside angles of the triangle.

So, the correct answer would be D.
